Intervention essentials

Getting the best out of subsea wells has always been important given the significant investment cost. This becomes especially true when field economics come under pressure. Having a subsea well intervention strategy is a key part of maximizing the value from these subsea assets and can often lead to higher returns.

With interventions ranging from downhole diagnostics to troubleshooting seabed equipment the strategy must focus on deploying the appropriate tools for the job. Utilizing purpose-built equipment and systems allows costs to also be appropriate for the job, making interventions more economical.

Collecting well critical data and performing regular well maintenance is common practice on land because it is not so cost prohibitive to do so. Now, these same well critical operations can be performed on deepwater wells at a cost that returns value to the well operator.

These new systems have been brought to the market with an enhanced focus on safety and operations integrity, which enables the intervention activities to be executed in a safe and efficient method. Wellbore interventions that once required a full drilling rig spread can now be performed from a similarly qualified monohull vessel.

The ability to perform the full spectrum of intervention activities on subsea wells in a safe, efficient and economical manner is essential to every deepwater operator’s portfolio.
